Abstract
The utility model belongs to the technical field of milling in the power industry and of metallurgical mechanical equipment, and mainly relates to a liner plate of a cylinder type ball mill. The liner plate (2) which adopts a stepped structure is arranged on the inner wall of a ball mill cylinder body (1), and the size of the liner plate is gradually reduced from the charging end to the discharging end. The liner plate adopts the stepped structure, which ensures synchronous abrasion of the liner plate of the ball mill cylinder body, thereby prolonging the effective using period of the liner plate by 20%; meanwhile, the material consumption is reduced and the labor intensity of workers is lowered.
Description
Technical field
The utility model belongs to power industry powder process and metallurgical machinery equipment technical field, relates generally to a kind of ball tube mill liner plate.
Background technology
As everyone knows, in metallurgical machinery equipment, grinding machine is most widely used plant equipment; The kind of grinding machine is a lot, can be divided into ball mill, rod mill, pebble plain, autogenous tumbling mill, semi-autogenous mill etc. according to the difference of milling medium; Wherein milling medium is that the grinding machine of steel ball is a ball mill; Ball mill has rotatable cylindrical shell, and antiwear lining plate is installed on cylinder inboard wall, forms the shell liner layer, puts into the technology steel ball in the shell liner layer; The operation principle of cartridge type low speed ball mill is: grinding machine is during with the rotation of certain rotating speed, is in the milling medium in the cylindrical shell owing to produce centrifugal force during rotation, causes between it and the shell liner and produces certain friction; This friction makes milling medium rotate with cylindrical shell, and arrives certain altitude.When himself gravity (actual is the entad component of gravity) during, just break away from the cylindrical shell impelling, thereby smash ore greater than centrifugal force.Simultaneously, in the mill running process, milling medium also has sliding phenomenon, and ore is also produced abrasive action; So ore obtains pulverizing under impact that milling medium produces and abrasive power synergy.Wherein, simplified liner plate is as the critical piece of directly withstand shocks power and abrasive resistance, and its material and structure have just determined the service life of ball mill.At present the abrasion-proof backing block structure used of cartridge type low speed ball mill mainly be adopt bolting band dovetail groove high manganese steel lining plate on cylinder inboard wall, and each piece liner plate consistent size; Because grinding machine all diminishes to discharge end ore grain size and concentration gradually from feed end, the impact and the attrition of liner plate also diminished gradually, so just caused lining board of grinder overall wear speed inconsistent, i.e. feed end quick abrasion, the discharge end wearing and tearing are slow; Like this with regard to having formed that the discharge end liner plate can also use and the feed end liner plate result that scraps of experience wear, and then cause the lining board of grinder Acceptable life to shorten and the waste of material, also increased the labour intensity that the workman changes liner plate; How overcoming the shortcoming that above-mentioned ball grinding machine lining board occurs, is the task that current urgent need solves in this area.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of ball tube mill liner plate, make the rate of wear such as the discharge end liner plate of ball mill barrel liner plate and the realization of feed end liner plate and wait service life, and then the whole service life of raising ball mill barrel liner plate.
Adopt following technical scheme for finishing foregoing invention content the utility model:
A kind of ball tube mill liner plate, described liner plate are positioned on the inwall of ball mill barrel, and described liner plate adopts stepped construction, and its liner plate size reduces from the feed end to the discharge end gradually.
A kind of ball tube mill liner plate that the utility model proposes, liner plate adopt stepped construction to guarantee that the wearing and tearing of grinding mill barrel liner plate are synchronous, make effective life cycle of liner plate improve 20%, have reduced material consumption simultaneously, have alleviated working strength of workers.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, grinding mill barrel, 2, liner plate, 3, bolt, 4, rubber blanket, 5, bowl type gland, 6, nut.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is illustrated:
As shown in Figure 1, a kind of ball tube mill liner plate, described liner plate is fixed on the cylinder inboard wall by clamping screw, locking nut, and described liner plate adopts stepped construction, and promptly its liner plate size reduces from the feed end to the discharge end gradually; Have the installation screw on described liner plate, the grinding mill barrel, bolt 3 passes installation screw, the bowl type gland 5 on liner plate, the cylindrical shell, and fastening by nut 6; Between bowl type gland 5 and grinding mill barrel 1, has rubber blanket 4.
Claims (1)
1. ball tube mill liner plate, described liner plate (2) is positioned on the inwall of ball mill barrel (1), it is characterized in that: described liner plate (2) adopts stepped construction, and its liner plate size reduces from the feed end to the discharge end gradually.
